Dear SKann.1,

the included patch antennas are:

1 x SlimLine A5020 FCC variant from Times-7

1 x SlimLine A5020 ETSI variant from Times-7

The PCB Near-Field antenna is a STM custom built antenna

• VSWR: 1.2 (typical)
• no far field (Gain < -20 dB)
• magnetic field is concentrated in the center of the antenna (see image)

The transmit power of the reader can be adjusted in the GUI.

Please refer to the GUI user manual for more information.

Cheers,
